must be set to the value of the parameter in the continued fraction, for .
- ufloat, array-like, shape
must be set to the value of the parameter in the continued fraction, for . (The element is not used).
The value of at which the continued fraction is to be evaluated.
The value of the continued fraction corresponding to the value of .

corresponds to a pole of , or is very close. .
dim1_ratnl_evalevaluates the continued fraction
for a prescribed value of .
dim1_ratnl_evalis intended to be used to evaluate the continued fraction representation (of an interpolatory rational function) produced by
